This article is a  great addition, in fact a ground breaking and makes it possible to precisely date whistles which previously was done by mare address, The best addition to the tools of dating J. Hudson & Co. Police whistles and none police whistles as G.P.O and other services.

For many years the dating system was based on 4 basic elements shapes of a whistle’s parts (see interlude ).
These are:  The Mouthpiece, The Loop, The address on Body and the one which one can not see without looking into the whistle itself that is the Diaphragm disk construction. Most advanced collectors are familiar with these and use to determine the date.

We learn that the address does NOT always correspond with date made , or serves as an always an accurate tool for knowing the exact year-date made.

Many marked 13 Barr St. where actually made later at 244 Barr St and stamped with the older address . This explains a 13 Barr st. address stamped whistle with a military date of 1910, 1911, 1912, 1913 for example.

  1. I have a J Hudson & Co whistle with The Metropolitan N.S.W. Police stamped on it along with the address being 244 Barr Street, Birmingham. I presume it is nickel plated. At the top the cap has a thick chain holder, and at the base it is the shorter version. Would I be right in saying this model would be about 1930? There is no serial number on it.

  2. I was interested to read about the dated military whistles. Your article mentioned that the 1906 miltary whistle is quite rare. I have a Hudson dated 1906 with the small crows foot under the Hudson patent. The 13 .Barr st address is in the same font as the the 1902 – 1905 whistle

  3. Hi, I have just come to own an old whistle and wonder if you can assist in dating it etc. It is brass with a very good patina and comes with a brass lanyard. It has stamped on the the round body ‘The Kinglet” and then underneath ‘Hudson’s Patent’ and then under that ‘L & S W …. (I cannot read the rest).
    I can send a photo if you require.
    I look forward to responses.
    Thanks , Kay

  4. Hello,
    I wonder if you can help me. I have an old The Metropolitan police tube whistle which seems to be unusual in that it gives the J Hudon &Co. address as Barr st. Hockley, without a street number. It does not appear to have been worn off, although most of the plate had been worn off the brass. I’d be happy to send you photos if you think this is an unusual item – I’m trying to date it. Kind regards, Paul

  5. I have a Metropolitan whistle which does not fit any of your descriptions. It is labelled THE Metropolitan. Below that there is a stamp which says N.P. There is no number for Barr Street, and no serial number either. Family lore says this could have been used in Nigeria by the police there. Would be grateful if you could shed some light on this.
    Many thanks

  6. I am trying to date what I believe was my Grandfathers whistle from 1st world war. There is not a date on it the word PATENT is straight letters but word is curved. there is a dot after 13. is there someone I can contact?
